drain radiator

I just had a radiator drain valve that would not drain. Leaving the radiator cap on, I slowly pulled the lower radiator hose from the radiator. I didn't get an anti freeze bath because the liquid flow was limited by the lack of venting. Actually the cap will vent a little, so you may want to cork up the radiator inlet to restrict the flow into a catch bucket.

thanks. good advice, I will follow. again thanks for the good tip.
